WILLIAM H. OREM, OF BALTIMORE, MARYLAND MILK BOTTLE HOOD Applicationfiledv June 25, 1932. Serial No. 619,345.

This invention relates to bottle-mouth covmilk for the purpose ofgetting the customer from the dairy which originally delivered the milkto the door of the customer, without sholwing that the hood has beentampered wit Another object of this invention is to provide a hood thatis especially useful for fitting over, under and around the mouth andbead of a bottle-neck so closely as to eliminate e entrance ofimpurities or defiling substances which might'tend to settle on thebottle-mouth, outside of the closing disc or stopper, if leftunprotected by the hood; also to protect the closing disc against suchdefiling or contaminating agencies, and from being removed byunauthorized persons.

Another object is to provide a bottle- .mouth-hood of material that issubstantially non-elastic or unstretchable while being so brittle thatit can be broken easily and thus removed by proper application of forceby the hand of the housewife or other person; and cannot be removedwithout being broken irreparably, whereby it gives substantial and veryimportant evidence, when unbroken, that the contents of the bottle areunadulterated by any substance which entered the bottle after the hoodwas originally placed and molded around the bottle-neck-bead.

A further object is to provide a thoroughly practical and effectivebottle-mouth protector which can be formed of comparatively inexpensiveand light material, by a rapid and efiicient means and method so thecost is reduced to the minimum for production, ap-

plication and transportation.

Other objects and important features are pointed out or implied in thefollowing details of description, in connection with the accompanyingdrawing in which:

Fig. 1 is a side elevation of a milk-bottle having applied thereon aninverted cup or unfinished hood of the composition from which the hoodsare molded, the cup being in vertical section.

Fig. 2 is an elevation or side view showing the finished hood on thebottle-mouth-bead, one-half of the bead, sealing disc andhood being invertical section. I

Fig. 3 is a view showing the finished hood partly removed, or in aposition where left after its removal was started, this view showing thebreaks in the hood, resulting from the brittleness or unstretchablenessof the smaller part of the hood while being forced over the larger partof the bottle-mouthbead, thereby showing that it was tampered with by anunauthorized person, unless it' was so broken by an authorized person.

Referring to the drawing in detail, in which similar numerals refer tosimilar parts in the several views, the invention is described in detailas follows:

The bottle-mouth-bead is shown at 1, and

its upper end terminates in the bottle-mouth which'has the usual closingor sealing disc 2 therein. The cup or unfinished hood is indicated at 3in Fig. 1, whereas, the finished hood is indicated at 3a in Fig. 2, andthe distorted and broken hood is indicated at 3b in Fig. 3. Likewise,the peripheral flange or skirt, of the unfinished, finished and brokencap, is shown at 4, 4a and 4b, in Figs. 1, 2 and 3, respectively.

In preparing the material for making the cap 01;,hood, wood pulporsimilar fibrous pulp is used, preferably spruce fibre pulp, and

is intermixed with parafiin or other suitable plastic waterproofingmaterial, in any suitable quantity or proportion for rendering the hoodbrittle and substantially unstretchable after it is molded and finishedon the bottle -mouth-bead.

In forming the unfinished hoods such as shown in Fig. 1, theabove-mentioned composition, or any suitable substitute therefor,

is molded into a cup having a flared wall or skirt; next, this skirt isfluted or plaited, by any appropriate means, the flutes or plaitsextending straight from bottom to top of the 2 I Me ia? skirt and beingslightly deeper at the lower movable only by breaking the part thatexmargin so the skirt is thereby rendered subtends under" the bead ofthe bottle.

stantially the same diameter at the bottom,

as at a plane near the top, from which lane 1t is upwardly and inwardlycurved to t the bottle-mouth snugly.

In applying and finishing the hoods when the bottles have been filled,and closed with the discs 2, the unfinished caps 3 are taken from asuitable bath of liquid or saturated steam or vapor, applied on thebottles as shown in Fig. 1, and then subjected to an inward orcentripetal force which is applied to all oints on-the outer peripheralsurface and at t e lower and middle parts, thereby completing themolding of'the hood and thus causing it to hug the bottle-mouth-beadsnugly; and, at the same time, heat is applied at a sufliciently hightemperature to quickly evaporate all the moisture and thereby render thehood so brittle or unstretchable that it cannot be removed from thebottle-mouthbead without being broken in one or more places, therebygivlng prima-facie evidence that it has been removed or partly removedfrom the bottle-mouth-bead.

Although I have described this embodiment of my invention quitespecifically, I have no intention of limiting my patent protection tothese'exact details of construction, materials or method, for theinvention is susceptible of numerous changes within the scope of theinventive ideas as implied and claimed.

What I claim as my invention is:

1. The method of forming a bottle-mouthhood, consisting in, firstprovidinga molded cup having a substantially cylindrical wall whichincludes fibrous and fusible materials; second, applying moisture to thecup for softening it; third, placing the cup of soffrom folds or tonedmaterial with its wall around the head of the bottle-mouth; and fourth,simultaneously applying centripetal pressure and heat suflicient tocomplete the moldingof the hood 1 around and under the bead and toevaporate the moisture and thus render the finished molded hood brittleso it cannot be removed from the head without breaking the fibres of thematerial which com oses the hood.

2. In combination wit a bottle having a bead around its mouth, a closingdisc in said mouth spaced below the upper extremity of the mouth, and abrittle and substantially unstretchable protecting hood formed of acomposition which includes plastic waterproofing and fibrous -materialsintermixed and permanently molded under high temperature into aninverted cup which is of substantially uniform thickness and snugly fitsover an being spaced from said closing disc and free laits and also freefrom adhesion to the ottle, whereby it is held on the bottle by itsinherent tenacity and is rearound and under said bead while I H.
